IMPROVEMENT IN SPRING-SEAT FflR VEHICLES.

TO ALL WHOM IT MAY eoncnnn;

Be it known that I, WIILLIAM HUGHES, of Brandon, in the county of Fonddu Lac, and State of Wisconsin, have invented a new and usefulImprovement in Spring-Seats for Vehicles, of which the following is afull, clear, and exact description, reference being bad to theaccompanying drawing, which makes part of this specification, and whichrepresents a view in perspective of my improved seat, with the outercasing ofene end removed to show the details of my invention.

It is the objecto f my invention to secure a seat for vehicles, which,while free to yield vertically, is restrained from swaying too muchlaterally, and to this end my improvement consists in so arranging a.sent between guides or ways that it shall be free to move vertically,and yet restrained in its lateral movements, while theseat rests upon.springs formed of cylinders of rubber arrangedsidewise between theguides.

The accompanying drawing shows one convenient way of carrying out myinvention.

The seat-board A is notched at the corners .to receive the standards orguides B, which have vertical grooves 12 on their inner sides. Thesegrooves receive the ends of shelves 0 C, which move freely up and downin them. Cylinders D1), of rubber or gutta percha, are fastened to theunder side of these shelves by wire at or other suitable means. Thelower series of cylinders D rest on the bed-pieces E, which support thestandards, and are-in this instance made of larger size than the upperseries D, which are fastened to the upper shelf C, but rest upon thelower one. The seat A rests directly on the upper shelves. Thisarrangement enables me readily to remove the seat, shelves, and springs,when required, without removing the inner casing F, which may be formedof tin or sheet-iron plates fastened to the guides so as to form a boxor chamber, in which the springs and shelves work. I ,The. inner casingF oniy extends to the height of the lower shelf. the remaining portionof the springs bein'gcovered by a. flap, F, attached to and moving withthe seat.

When the springs are suddenly compressed by the jolting of the vehiclethe upper springs are compressed first, and 'as the cylinders are smallthe seat sinks but a short distance before the upper cylinders areflattened; the impulse is then given to the lower springs, which'are oflarger diameter and greater range. The seat is thusrenderedsuflicientlyelastic, while its range of motion is not too great for comfort.

What claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, substantially as described, of a seat, capable ofmoving freely vertically between its guides, with a series of supportingcylindrical rubber springs arranged sidewise within their guides.

2. The combination, as described, of the rubber cylinders, with theshelves sliding vertically in their guides.

3. Making the low'ertier of springs of larger diameter than the upper,as described, for the purpose set forth.

In-testimony whereof I have hereunto subscribed myname.
